Each battery is bench-tested in our workshop — we verify actual capacity, cycle count (under 100 cycles), cell balance, and run a full charge/discharge cycle. Only packs that pass our strict criteria are listed on nnlaptops.com. This is your peace of mind when ordering from Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot — we ship nationwide via TCS or Leopards.
Why choose the genuine Apple battery over third-party options?
- Perfect fit: Original casing and connector — no modifications needed.
- Reliable BMS: No 'service battery' warnings or wrong capacity readings.
- Safety: Original cells are less prone to swelling; we check every pack for swelling before sale.
- Resale value: Keeping original parts maintains your MacBook's value.
Compatibility — which laptops does this battery fit?
This 99Wh 6-cell internal battery is a direct OEM replacement for the following Apple laptops:
- MacBook Pro 15 Retina Mid 2015 A1398
- MacBook Pro 15 Retina 2014 A1398
Match the OEM part number on the sticker of your current battery before ordering. If your old battery part number isn't on this list but the laptop is, message us — there are often three or four interchangeable part numbers per chassis. Send a picture of your old battery on WhatsApp 0314 4000131 and Sayam will confirm compatibility within minutes.
Battery health — what we test before shipping
Every battery on our shelf goes through a 5-point test before listing:
- Capacity — we measure actual usable Wh and only ship packs at 95%+ of rated capacity.
- Cycle count — read from the embedded BMS chip; we don't sell anything over 100 cycles.
- Cell balance — all 6-cell internal cells within 50mV of each other.
- Charge/discharge cycle — verified full cycle without thermal anomaly.
- Visual — no swelling, no bulging, no scorched contacts.
Our bench-testing goes beyond basic diagnostics. We simulate a typical user load to ensure the battery holds charge under real-world conditions. This is why customers from across Pakistan trust us for original MacBook parts.
Installation — how to swap the battery
Internal 6-cell batteries on modern Apple laptops require opening the back panel (8-12 Phillips screws, sometimes Torx T5). Disconnect the AC adapter, unscrew the panel, locate the battery connector on the board, gently lift the ribbon connector latch, unscrew the battery hold-down screws, lift out the old pack, and reverse the steps with the new one. Total time: 10-15 minutes.
Free installation in shop
If you're in Lahore, bring the laptop to Hafeez Center — installation is free with battery purchase. We'll also calibrate the new pack (full charge → full discharge → full charge) so Windows / macOS reads the correct capacity from day one. For DIY installers, we include a step-by-step video link via WhatsApp after purchase.
After installation, run a full cycle to let the BMS calibrate. You'll notice the battery meter immediately showing accurate percentage. If you face any issues, Sayam offers remote support via WhatsApp.
Real-world battery life — what to expect
With this 99Wh pack and balanced Windows / macOS settings (70% brightness, Wi-Fi on, mixed use), expect:
- Web + Office work: 5-7 hours
- Video playback: 6-8 hours
- Code compilation / Photoshop: 2-3 hours
- Gaming or heavy GPU load: 60-90 minutes
These figures match Apple / Dell / HP / Lenovo published specs for the listed models. If your old battery was giving you 2 hours, the new one will restore the original full runtime. Battery life also depends on macOS version and background apps — we recommend reducing screen brightness and closing unused programmes for maximum backup.

Warranty — what you're protected against
Every battery carries our 30-day check warranty. If the pack fails to charge, shows wrong capacity in Windows / macOS, drops below 85% of rated Wh in our diagnostic, or develops any swelling within 30 days, bring it back to the shop with the invoice for full replacement or refund. No questions asked within the warranty window.
The warranty covers manufacturing defects and hidden damage not visible at purchase. It does not cover physical abuse (dropping, liquid damage) or wear from exceeding the rated cycle life.
Frequently asked questions
Will the laptop recognise this battery in Windows / macOS?
Yes — every battery we sell is BMS-flashed with the correct cell-pack ID for the laptop, so Windows / Lenovo Vantage / Dell Power Manager / macOS Battery Health show full information including cycle count and design capacity. No 'plugged in, not charging' driver errors.
How long will the new battery last?
A fresh quality cell-pack should give you 400-600 full charge cycles (about 2-3 years of daily use) before noticeable capacity drop. Avoid leaving the laptop plugged in at 100% all day — keep it cycling between 40% and 85% for longest cell life.
How much battery backup will I get on my MacBook Pro 15 Retina Mid 2015 A1398?
With this 99Wh pack at default Windows balanced settings, expect 5-7 hours of mixed-use battery life (web, Office, video). Brightness at 70%, Wi-Fi on, no heavy GPU workload. Gaming or compiling drains in 90-120 minutes — that's normal for any laptop battery this size.
Is this a genuine OEM battery or aftermarket?
Our stock comes in both genuine Apple pulls (tested cells, original casing, often the higher price) and high-grade A-class compatible cells (tested for capacity at 95%+ of rated Wh). Tell us which you want on WhatsApp 0314 4000131 — both carry the same 30-day check warranty.
What is the price of this battery? Is it available in Pakistan?
The current price for this genuine Apple battery is Rs. 18,599. We ship all over Pakistan, including Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, and Sialkot. Order via WhatsApp for fastest service.
